A Study of the Reactions of 6-Thia-Nido-Decaborane(11).
Abstract
Reactions of the heteroborane, 6-thia-nido-decaborane (11), have been examined under a variety of conditions with the specific objective of determining the ability of this compound to hydroborate alkenes and alkynes. Under room temperature conditions, reaction with alkenes occurred exclusively at position 9 of the thiaborane cage. Steric factors influence the course of the reaction with respect to the organic moiety, and evidence is cited as to reactions reversibility. At higher temperatures, additional alkyl groups could be attached to the thiaborane cage as a consequence of multiple hydroboration steps. The results are consistent with a mechanism in which hydroboration occurs only at position 9 of the cage followed by isomerization caused by the fluxional nature of the heteroborane cage. (Author)
